Description

Ginsenoside Re is a ginsenoside extracted from Panax ginseng, known for its skin benefits and therapeutic potential. It is used in cosmetics for its anti-aging and antioxidant properties.

Chemical Composition and Structure:

Active Ingredient: Ginsenoside Re is a triterpenoid saponin, part of the dammarane class of ginsenosides.
Molecular Weight: Approximately 788.8 g/mol.
Structure: Characterized by a dammarane skeleton with sugar groups, typically glucose and rhamnose.

Physical Properties:

Appearance: White or pale yellow powder.
Odor: Mild, characteristic of ginseng.
Solubility: Soluble in hot water and some organic solvents; solubility may vary depending on the formulation.
pH: Generally stable within the pH range common in cosmetic formulations.

Production Process:

Extraction: Ginsenoside Re is extracted from Panax ginseng roots using solvent extraction or supercritical fluid extraction methods.
Purification: The extract is purified to isolate ginsenoside Re.
Formulation: The purified ginsenoside Re is incorporated into cosmetic products or used in research.

Applications:

Skincare Products: Ginsenoside Re is known for its anti-inflammatory, antioxidant, and anti-aging properties, helping to improve skin elasticity, reduce the appearance of wrinkles, and promote healthy skin.
Cosmetic Formulations: Commonly used in anti-aging creams, serums, and other products designed for skin rejuvenation and care.

Environmental and Safety Considerations:

Environmental Impact: Sustainable practices in the extraction and production of ginsenoside Re are essential to minimize environmental impact.
Safety: Ginsenoside Re is generally considered safe for use in cosmetics. However, individuals with allergies or sensitivities to ginseng should exercise caution.

INCI:


Antioxidant agent. Ingredient that counteracts oxidative stress and prevents cell damage. Free radicals, pathological inflammatory processes, reactive nitrogen species and reactive oxygen species are responsible for the ageing process and many diseases caused by oxidation.

Humectant. Hygroscopic compound used to minimise water loss in the skin and to prevent it from drying out by facilitating faster and greater absorption of water into the stratum corneum of the epidermis. The epidermis is the most superficial of the three layers that make up human skin (epidermis, dermis and hypodermis) and is the layer that maintains hydration in all three layers. In turn, the epidermis is composed of five layers: horny, the most superficial, granular, spinous, shiny, and basal. Humectants have the ability to retain the water they attract from the air in the stratum corneum and have the function of moisturising the skin. They are best used before emollients, which are oil-based.

Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
